fdisk is a command-line partitioning utility supplied as part of util-linux. It provides an interactive interface for creating and modifying disk partition tables.
The program is designed primarily for human interaction rather than scripted partitioning. It understands both modern GPT layouts and traditional MBR partition tables.
fdisk takes device topology and sector alignment into account when choosing default partition boundaries, helping to produce sensible layouts on modern storage devices.
This is free and open source software.
Key Features
- Creates, deletes and modifies partitions through an interactive command interface.
- Supports GPT, MBR/DOS, Sun, SGI and BSD disk labels.
- Displays existing partition layouts and detailed information about block devices.
- Creates partitions using sector numbers or human-readable size specifications.
- Automatically aligns partitions according to the storage device’s I/O topology.
- Edits partition types, names, UUIDs and other label-specific attributes where supported.
- Can display unused regions of a disk to help identify available partitioning space.
- Detects existing filesystem, RAID and partition-table signatures and can wipe conflicting signatures when requested.
